The open ends of the clamping openings form V shape. The clamping openings, the clamping and containing space, the plugging foot of the terminal, and the center line of the terminal are formed on the same axial line. The utility model can be widely used for the electronic product.

Description

Improved terminal

The utility model relates to a kind of electrical terminal part, refers to that especially a kind of main folder sheet of clamping part is provided with the terminal of sub-folder sheet.

The existing terminal plug connector that directly is hubbed on the printed circuit board (PCB) can be divided into two kinds of integral type and complex formulas, and wherein complex formula such as Fig. 1 are to be made up of two or two above members, and volume is big, complex structure, seldom employing; The small volume structure of integral type is simple, as shown in Figure 2, system forms with sheet metal roller volume, the clamping part section is the C type, utilizes the characteristics of its internal diameter less than the latch diameter of public access spare and clamping part periphery distortion elastic force, reaches fixed purpose in order to the latch of clamping public access spare, but its major defect is after repeatedly using, yielding, cause loose contact, influence the signal transmission; Another kind of integral type such as Fig. 3, the clamping part side is

Shape is utilized the latch of the elastic force clamping public access spare of the tortuous metal sheet of clamping part, but that its shortcoming is a procedure is many, the cost height, and the size of terminal lateral width is bigger, is not suitable for the less matrix form terminal grafting member of spacing and uses.By last explanation, terminal structure has improved necessity in fact.

The purpose of this utility model is because there is above-mentioned various shortcoming in existing terminal, improves through years'experiences research, provide a kind of not yielding, chucking power is constant, guarantee the signal transmission quality and easily process, the terminal of material saving.

The purpose of this utility model is achieved with following technical proposals; Structure is through improved terminal, include clamping part inserting foot etc., the clamping part that it is characterized in that terminal is to biasing on one side, the main folder sheet of clamping part is provided with short sub-folder sheet, the biasing of main folder sheet lower end and clamping part oppositely bends, the upper end of main folder sheet and sub-folder sheet forms contour folder mouth, and forms a clamping accommodation space between main folder sheet and the sub-folder sheet, and the folder mouth is established V-shaped openend; Its center line of the inserting foot of folder mouth, clamping accommodation space and terminal forms on same axis.

Technique scheme, its clamping accommodation space, the latch that can make terminal clamping part and public access spare has more contact point when pegging graft, to guarantee the signal transmission; So folder mouthful, clamping accommodation space and terminal inserting foot three's center line is formed on the same axis, have more tough inserted sheet ability to bear, can satisfy instructions for use not yielding, that chucking power is constant thus, and easily process, the material saving.

Below by drawings and Examples the utility model is described further again;

Fig. 1, be the structural representation of existing complex formula terminal;

Fig. 2, be the structural representation of existing simple type terminal;

Fig. 3, be the structural representation of existing N type terminal;

Fig. 4, be the schematic perspective view of the utility model terminal;

Fig. 5, be the schematic side view of the utility model terminal;

Fig. 6, be the grafting shape schematic diagram of the utility model terminal.

Shown in Fig. 4,5, the similar used row's shape terminal that forms by the sheet metal punching out of preferred embodiment of the present utility model, wherein, the hypomere of terminal is set as the inserting foot 3 of pin shape; Position, stage casing two sides are provided with recessed edge 2 conducts and the chimeric location structure of terminal case (not shown) of arc of symmetry; And it is to form a trace biasing situation in the lower end of the clamping part 1 of terminal upper portion position to one side backfin than special feature, main folder sheet 11 upper punches by terminal clamping part 1 cut short sub-folder sheet 12, the reverse work one arc bending of the biasing of main folder sheet 11 lower ends and clamping part 1, main folder sheet 11 forms contour folder mouth 13 with the upper end of sub-folder sheet 12, and between main folder sheet 11 and sub-folder sheet 12, form a clamping accommodation space 14, and the antelabium 121 of the antelabium 111 of main folder sheet 11 upper ends and sub-folder sheet 12 upper ends all is set as the arc with appropriateness, make the V-shaped openend of folder mouthfuls 13, and folder mouthfuls 13, the center line of clamping accommodation space 14 and inserting foot 3 is formed on the same axis.

The situation of briefly installing and using of the present utility model is like this; Utilize inserting foot 3 covers to insert in the jack, give the solid welding combination with soldering again; Utilize the recessed edge 2 of arc and the chimeric location of terminal case at position, stage casing; When the latch 4 of public access spare is desired to combine with clamping part 1, make latch 4 pass folder mouthfuls 13 and be intercalated in the breach 112 of main folder sheet 11 bottoms with pin front end 41, the latch 4 of public access spare and terminal clamping part 1 contact the firm combination of multiple spot, transmit to guarantee signal; The center line of folder mouthfuls 13, clamping accommodation space 14 and terminal inserting foot 3 is formed on the same axis again, so and more tough slotting pressure ability to bear arranged; And generally speaking, terminal clamping part 1 is to go out short sub-folder sheet 12 by 11 punchings of main folder sheet, advantage of so handling ease is arranged, saving material, and it utilizes the bending effect of main folder sheet 11, sub-folder sheet 12 and respectively have the ability of strain, so can guarantee constant, the on-deformable characteristic of chucking power.

Claims (1)

1, structure is through improved terminal, include the clamping part inserting foot, the clamping part that it is characterized in that terminal is to biasing on one side, the main folder sheet of clamping part is provided with short sub-folder sheet, the biasing of main folder sheet lower end and clamping part oppositely bends, the upper end of main folder sheet and sub-folder sheet forms contour folder mouth, and forms a clamping accommodation space between main folder sheet and the sub-folder sheet, and the folder mouth is provided with the openend of V-arrangement; Its center line of the inserting foot of folder mouth, clamping accommodation space and terminal forms on same axis.
